I use the following gear for motion control. These companies have been instrumental in helping me to accomplish what I have, and for that I am most thankful. A small portion of your purchase goes to me without changing your cost when you click these links, which is nice because all of my projects are self funded (so you're helping me stay in the game by clicking these before you buy your gear).
June 18th, 2016 - note: I will be updating this portion of the website to give the pros and cons of these different systems shortly. All three have most generously sent me gear and I want to thank them!
